'A coding Mozart': Boy, 7, gets job offer from Russian IT firm

On his videos, Sergey appears fresh-faced and smiling enthusiastically. Speaking in Russian and sometimes in slightly broken English, he goes through coding challenges step-by-step. His YouTube channel has more than 3,500 subscribers, interested in learning programming languages Python and Unity, or who want to hear more about neural networks, which underlie many artificial intelligence tools. Mr Mandik said Sergey showed not only remarkable developer skills but also "equally unique" skills in teaching. "For me, he is kind of a Mozart."
